The facility, which has been provided by pharmaceutical company GlaxoSmithKline, will be operated by leading anti-doping experts from King’s College London and supported by scientists from around the world.

LOCOG Chief Executive Paul Deighton said: "Working with one of the world’s best pharmaceutical companies and one of the country’s leading universities, we have been able to create a facility to successfully and efficiently process 6,250 tests during the Games which has never been done before.

"As we unveil the anti-doping lab we recognise the importance of a robust testing system and continue to show that London is ready to stage a successful Games."

Over 1,000 LOCOG staff will work within the anti-doping process and a team of more than 150 anti-doping scientists will carry out the testing at the laboratory, led independently by Professor David Cowan from the Drug Control Centre at King’s College London.

The laboratory will be in operation 24 hours a day, seven days a week during the Games, and was today visited by Hugh Robertson, Minister for Sport and the Olympics.

Sir Andrew Witty, CEO of GlaxoSmithKline, said: "As a science-based organisation, GSK is well placed to help deliver the scale and cutting edge technology required to run an operation like the anti-doping facility for London 2012.

"We have worked with King’s to put systems in place to enable this laboratory to test more samples than any previous Games and at the same time developing a blueprint for doping operations at future Games."

The Anti-Doping process during the London 2012 Games will create a legacy of knowledge about operations and processes. In July 2011, GSK signed an agreement with the World Anti-Doping Agency (WADA) to share information about its medicines in development, while LOCOG will debrief on all processes.Key Statistics:
